You remember the first Back to the Future movie, right? In it, Marty McFly (Michael J. Fox) went back in time to save Doc Brown and fix his parents relationship so he could be born in the future. At the end of the movie it all turned out well for him and his family and things seemed wrapped up neatly — except for that whole thing about his kids at the end.

Of course, you also remember what happened to Biff Tannen, the bad guy bully who made life hell for George McFly and by the end of the film in the present, had been reduced to a humble guy waxing Marty’s truck. Well, it seems the makers of this parody video, found over at College Humor, have other ideas in mind fo Biff.

See if you can spot the difference between how the movie ended and how this video thinks the movie would have ended. We’re pretty sure you won’t have much trouble figuring it out.

Check out the video after the break. And remember kids, time travel isn’t for everyone so please, be careful.
